From the introduction, each row and each column of the 6x6 Word Square
contains the characters MONEY and a blank cell in some order, so that no
character or space can be repeated in a row or a column. By clue 5, E is the
2nd letter across row 4; while by clue 11, E is the 2nd letter across row 2.
Therefore, the row 2 E is in column 2 and the row 4 E in column 3; or the
row 2 E is in column 3 and the row 4 E in column 2. Testing the latter case,
by clue 1, the M in column 2 would be in row 3. Then in clue 6, the space
and M in row 2 would be to the right of the E--impossible, since the space
must precede the E, which is the 2nd letter in row 2. So, in clues 5 and
11, the row 2 E is in column 2 and the row 4 E in column 3. By clue 1, the
M in column 2 is in row 1. By clue 10, the M in row 5 cannot be in column 2
and must be in column 1. Then the column 1 E is in row 6 (clue 7). By clue
3, O is the 4th letter in row 1; while by clue 8, O is the 2nd letter down
column 4. The O in row 1 must be in column 5. In clue 12, O and M are
either in rows 2 and 3 of column 3 or in rows 5 and 6. Trying O and M in
rows 2 and 3 of column 3, the column 4 O would be in row 3 (8). The
row 2 space and M in clue 6 then could not be in columns 4 and 5 (2) and
would be in columns 5 and 6. Y in column 5 would be in row 3 (2). Space
in column 4 would be in row 1 (8). E in row 3 would be in column 6--but
there would then be no way for an E to appear in row 1. Therefore, in clue
12, O and M are not in rows 2 and 3 of column 3 and must be in rows 5 and 6.
By clue 8, the column 4 O is in either row 2 or row 3. If the column 4 O
were in row 2, space and M in row 2 would be in columns 5 and 6 (6). Y in
column 5 would be in row 3 (2). Since the row 1 E then couldn't be in
column 4 (13), the row 1 E would be in column 6. The column 5 E would be
in row 5, with the column 4 E then in row 3 below the O, followed by N in
row 4 (13). However, there would then be no way for an M to appear in column 4.
So, in clue 8, the column 4 O is in row 3. By clue 13, the E and N down column 4
are in rows 1 and 2 or in rows 5 and 6. If the column 4 E and N were in rows
1 and 2, the row 2 space and M would be in columns 5 and 6 (6). The column 4
M would be in row 4. The column 5 M would be in row 3 and would be the 2nd
letter down column 5--no (2). Therefore, by clue 13, the E and N down column
4 are in rows 5 and 6. The row 5 Y isn't in column 5 (2) or column 6 (9)
and is in column 2. If the column 6 E were in row 3, there would be no
place for an E in column 5; the column 6 E is in row 1, with the column 5
E in row 3. Then by clue 2, Y in column 5 is in row 2. M in column 5 is
in row 4, with N then in row 5 and space in row 6. Space in row 5 is in
column 6. By clue 6, in row 2, space is in column 3 and M in column 4.
M in column 6 is in row 3. By clue 8, space in column 4 is in row 1, with
Y in row 4. N cannot go in row 3, column 3 (14) and is in row 1 with Y
in row 3. Y in column 1 is in row 1. Y in column 6 is in row 6. Then O
in row 6 is in column 2. The space in column 1 is in row 4, with the space
in column 2 in row 3 (4). N in row 3 is in column 1, with O in row 2
completing column 1. Row 2 has N in column 6. Column 6 has O in row 4.
The row 4 N is in column 2. In sum, Word Square 12 is filled as
follows:
